Guillaume Grando (born in 1978 in Bagnolet, France) lives and works in Biarritz, France.

A multidisciplinary artist, he has been drawn from an early age to hip-hop culture, architecture, design, and art. At the age of 12, he began painting on various surfaces, and in 1995 he founded the HV collective, exploring calligraphy, typography, graffiti, graphic design, and music production.

He graduated from the École Supérieure des Métiers Artistiques in Montpellier in 1997 and developed an independent career marked by international collaborations.

Starting in 2000, Guillaume Grando, under the pseudonym SupaKitch, began studio work, exploring painting on canvas as well as resin and wood sculpture. His style evolved toward abstraction, blending organic forms, architecture, music, and calligraphy.

His work took a new direction after a visit to the Musée Fabre in 2007, where he discovered Pierre Soulages’ “outrenoir,” which influenced his shift toward abstraction.

In 2008, he moved to New York, where his work absorbed a wide range of influences, including Japanese aesthetics. Gaining attention, he exhibited in New York, Miami, Denver, Mexico City, Paris, Taipei, Beijing, and Shenzhen.

Around this time, he also began spending time in Biarritz, drawn by the ocean and surf culture.

In 2011, his encounter with Paul Lefèvre (Son of Cobra) introduced him to the use of resin, a material that would become central to his practice.

Upon returning to Paris in 2012, he briefly explored tattooing, marking a return to drawing and figuration, while continuing to be invited to exhibit in the United States and Mexico.

In 2016, he settled permanently in Biarritz and focused his research on resin and pigments, exploring randomness, gloss, reflection, and depth.
